Description

BACKGROUND

The present disclosure relates to a light emitting diode system, and especially relates to a light emitting diode system receiving a wireless signal.

Description of Related Art

Currently, there are two types of the related art light emitting diode systems: the serial-type light emitting diode system and the parallel-type light emitting diode system. Both the serial-type light emitting diode system and the parallel-type light emitting diode system need to use a plurality of power transmission lines and signal transmission lines, which waste wires. Afterwards, the related art technology which transmits the lighting signal through the power transmission line is provided to save the signal transmission lines, wherein the lighting signal includes a lighting data and a data.

The local data has to be burned into the light emitting diode driving apparatus when the light emitting diode driving apparatus of the light emitting diode system is manufactured. The light emitting diode driving apparatus checks whether the data of the lighting signal is the same with the local data of the light emitting diode driving apparatus when the light emitting diode driving apparatus receives the lighting signal mentioned above. The light emitting diode driving apparatus drives the light emitting diodes of the light emitting diode system to light based on the lighting data of the lighting signal if the data of the lighting signal is the same with the local data of the light emitting diode driving apparatus.
